* fix similar typos to successfullColy Li2009-01-08
| | | | | | | | | | | | | | | | | | | | | | When I review ocfs2 code, find there are 2 typos to "successfull". After doing grep "successfull " in kernel tree, 22 typos found totally -- great minds always think alike :) This patch fixes all the similar typos. Thanks for Randy's ack and comments.

| | |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 38617c64 ("RDMA/addr: Add support for translating IPv6 addresses") broke the build when CONFIG_IPV6=n, because the ib_addr module unconditionally attempted to call ipv6_chk_addr() and other IPv6 functions that are not defined when IPv6 is disabled. Fix this by only building IPv6 support if CONFIG_IPV6 is turned on, and add a Kconfig dependency to prevent the ib_addr code from being built in when IPv6 is built modular.

RFC 5046 refers to these PDUs as "unexpected". NOP-In PDUs with itt=RESERVED and Asynchronous Message PDUs occupy this category. The amount of active "unexpected" PDU's an iSER target may have at any time is governed by the MaxOutstandingUnexpectedPDUs key, which is not yet supported. Currently when an iSER target sends an "unexpected" PDU, the initiators recv buffer consumed by the PDU is not replaced. If over initial_post_recv_bufs_num "unexpected" PDUs are received then the receive queue will run out of receive work requests entirely.

| | * | | | | IB/ipath: Don't count IB symbol and link errors unless link is UPDave Olson2008-12-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implement the ignoring of ibsymbol errors and linkrecover errors while the link is at less than INIT (long needed), to get accurate counts. Particularly an issue when doing non-IBTA DDR negotiation with chips from vendors that do not support IBTA mode negotiation. If the driver is unloaded, and there is a delta, the adjusted counters are written back to the chip, so they stay adjusted across driver reload.

This is calculated correctly for the WQE sent after the first request message but not on subsequent requests if the RDMA read is resent.

For UD loopback packets, this structure is allocated and freed for each packet. This patch changes that to allocate/free during QP creation and destruction.
